When I double-click it, it runs but first it opens Terminal.app and starts a session. I played with calling it from Applescript but without success. Can I make a bash file that doesn't start a terminal session?

Sorry, it's not Ada. It's Applescript. The Applescript compiler bundles this up nicely as a double-clickable application bundle and does what I want. (The dialog box at the end is a little gratuitous.) afplay plays any audio file.

For some time I have taken seriously the claim that sitting for long periods of time is unhealthy, and consequently I set my computer to announce the time every half hour at which time I am *supposed* to get up and run in place for one minute. I believe that this is a simple version of interval training and can actually cause me to lose a little weight. The problem is that I have to watch an analog on-screen clock to see when to stop and this does not always have a background that makes the clock easy to see, plus I have to stick next to the computer. Using a utility, I launch this program with a simple key combination.

I _want_ to start it myself each time, approximately every 30 minutes, and it is designed to stop running after one minute. See my "running" post above.

The Applescript works perfectly but it's not Ada. :-( And I still don't know how to solve my original problem, how to run Ada program without a terminal session starting.
